15% of what number is 39 i need the equation and it worked out

There isn't really an equation you just divide...

15%/39= 0.00384615384 

I hope this helps!!

X * 15/100 = 39 

divide both sides by 15/100

X = 39 / 15/100

and when dividing fractions you flip the second fraction upside down and multiply it

X = 39 * 100/ 15 

X = 260
